Attempting to bring my boiler into my home automation suite but failing at the Modbus part of it. What I have is a Honeywell Sola controller which requires a login string of "sola" to be entered before any coils or registers can be written. The link to the document that I've been working off of is:
https://customer.honeywell.com/resources/Techlit/TechLitDocuments/65-0000s/65-0310.pdf
It looks like the address is hex 00B1, decimal 0177. Using QModMaster to attempt writing, but getting an illegal function error. Can anyone point me in the right direction?
Thanks in advance...I am a real noob to Modbus.
